Description

Method and device for determining signal quality information of frequency points

Technical field

This application relates to the field of communication technology, and in particular to a method and device for determining signal quality information of frequency points.

Background technique

After the terminal device accesses the serving cell, it needs to perform neighboring cell measurement to finally obtain the signal quality information of the frequency point used by the neighboring cell, so that the network device can select a carrier for the terminal device based on the signal quality information, and finally realize cell reconfiguration. Select or switch. Among them, the neighboring cell measurement types include intra-frequency measurement, inter-frequency measurement, and inter-system measurement.

Co-frequency measurement is the measurement of the signal quality in the first type of neighboring cell by the terminal equipment. The frequency used by the first type of neighboring cell is different from the frequency used by the serving cell (that is, the working frequency of the terminal equipment). )the same.

Inter-frequency measurement is a measurement of the signal quality in the second-type neighboring cell by the terminal device, and the frequency used by the second-type neighboring cell is different from the frequency used by the serving cell.

The different system measurement is the measurement of the signal quality in the third type of neighboring cell by the terminal equipment, and the type of the mobile communication system where the third type of neighboring cell is located is different from the type of the mobile communication system where the serving cell is located. Since different types of mobile communication systems allocate different frequency bands, the frequency used by the third type of neighboring cell is different from the frequency used by the serving cell.

When the terminal equipment performs inter-frequency measurement or inter-system measurement, it needs to be implemented through a measurement gap (gap), as shown in Figure 1. Since the terminal equipment suspends service transmission in the measurement gap, the service throughput rate of the terminal equipment is lost. In addition, terminal equipment usually needs to measure multiple frequency points, and the time consumed to measure each frequency point (generally several hundred milliseconds (ms), such as 480ms, 240ms, etc.) is much longer than the time for measuring gap (generally 6ms). Therefore, terminal equipment needs multiple measurement gaps to complete inter-frequency measurement or inter-system measurement. Therefore, it takes a long time for network equipment to obtain signal quality information at each frequency point, which further extends the time for network equipment to select a carrier for terminal equipment. Affects the gain of carrier selection.

The embodiments of the present application will be described below in conjunction with the drawings.

FIG. 2 shows the architecture of a possible communication system to which the method for determining signal quality information of frequency points provided by an embodiment of the present application is applicable. Referring to FIG. 2, the communication system includes: a network device 201 (a network device 201a, a network device 201b, and a network device 201c in the figure), and a terminal device 202.

The network device 201 is responsible for providing wireless access-related services for the terminal device 202, realizing wireless physical layer functions, resource scheduling and wireless resource management, quality of service (QoS) management, wireless access control, and Mobility management (such as cell reselection and handover) functions.

Each network device 201 is responsible for managing at least one cell. As shown in the figure, the network device 201a is responsible for managing cell A and cell C, the network device 201b is responsible for managing cell B, and the network device 201c is responsible for managing cell D.

In this communication system, each cell uses a corresponding frequency point to provide access services for terminal equipment. It should be noted that the frequency points used by different cells may be the same or different. For example, cell A uses frequency 1, cell B uses frequency 2, cell C uses frequency 3, and cell D uses frequency 4. In addition, in the communication system, the types of mobile communication systems to which different cells belong may be the same or different. For example, a mobile communication system, cell A and cell C belongs to the fifth generation (The 5 ^th Generation, 5G) mobile communication system, a mobile communication system, cells B and D belong to the fourth generation (The 4 ^th Generation, 4G) . In addition, different cells belonging to the same mobile communication system can also use mobile communication technologies of different standards. For example, cell A may use frequency division duplex (FDD) communication technology, and cell C may use time division duplex (TDD) communication technology. In addition, in order to increase the data transmission rate of the terminal device 202 and the system capacity of the communication system, the communication system may use carrier aggregation (CA) technology.

The terminal device 202 is a device that accesses the network through a cell managed by the network device 201.

The network device 201 and the terminal device 202 are connected through a Uu interface, so as to realize the communication between the terminal device 202 and the network device 201.

The method provided in the embodiment of the present application is applicable to a multi-frequency scenario, that is, a cell in a communication system uses at least two frequency points. In order to ensure the communication quality and service transmission efficiency of the terminal device 202 that accesses the serving cell, the network device 201 that manages the serving cell needs to select a carrier for the terminal device 202 according to the signal quality information of each frequency point to realize cell reselection. Or switch.

It should also be pointed out that the communication system shown in FIG. 2 is taken as an example, and does not constitute a limitation on the communication system to which the method provided in the embodiment of this application is applicable. The method provided in the embodiment of this application can be applied to a multi-frequency scenario. Various communication systems.

Take cell A and cell C use frequency point 1, cell B and cell D use frequency point 2, and terminal device 202 accesses cell A (that is, cell A is the serving cell of terminal device 202) as an example for description:

In the process of cell reselection or handover of the terminal device 202, the network device 201a needs to obtain the signal quality information of frequency 1 and frequency 2, so as to select the terminal device 202 with the best signal quality information or meet the set conditions Finally, the neighboring cell using the target frequency will be the target cell for cell handover of the terminal device 202, or the serving cell using the target frequency will continue to serve the terminal device 202.

In the traditional method, the network device 201a needs to perform neighbor cell measurement through the terminal device 202 to obtain signal quality information of frequency point 1 and frequency point 2. The specific process includes:

The network device 201a sends measurement configuration information to the terminal device 202, where the measurement configuration information includes frequency points to be measured, a list of cells to be measured, signal quality parameters to be measured, reporting methods, and so on.

Optionally, the measurement configuration information may be carried in an RRC connection reconfiguration (RRC connection reconfiguration) message. The frequency points to be measured can be frequency point 1, or frequency point 2, or frequency point 1 and frequency point 2. When the frequency point to be measured includes frequency point 2, the measurement configuration information may also include measurement gap configuration information.

After receiving the measurement configuration information, the terminal device 202 may perform neighbor cell measurement according to the content included in the measurement configuration information. For example, when the measurement configuration information includes frequency point 1 (same frequency), the terminal device 202 needs to perform the same frequency measurement according to the content in the measurement configuration information; when the measurement configuration information includes frequency point 2 (different frequency) At this time, the terminal device 202 needs to perform inter-frequency measurement or inter-system measurement according to the content in the measurement configuration information.

After the terminal device 202 completes all measurements, it obtains the signal quality information of frequency point 1 and/or frequency point 2, and then sends a measurement report to the network device 201a, where the measurement report includes the obtained frequency point 1 And/or the signal quality information of frequency point 2.

The network device 201a selects a target frequency point for the terminal device 202 according to the obtained signal quality information of frequency point 1 and/or frequency point 2, and then selects a target carrier from the carriers corresponding to the target frequency point, and then completes Cell reselection or handover.

It should be noted that when the terminal device 202 is a CA user, the network device selects multiple target carriers for the terminal device. Wherein, the multiple target carriers may correspond to the same target frequency point, or may correspond to different target frequency points, which is not limited in this application.

As we all know, the terminal device 202 does not need to switch the operating frequency when performing co-frequency measurement, so the terminal device 202 can perform co-frequency measurement while performing service transmission. Therefore, the terminal device 202 does not need to suspend service transmission when performing co-frequency measurement. The service transmission of the terminal device 202 will not be affected, and there will be no time delay in the process of co-frequency measurement. However, when the terminal device 202 performs inter-frequency measurement or inter-system measurement, it needs to suspend service transmission in the measurement gap. In addition, the time consumed by measuring each frequency point (generally several hundred ms) is much longer than the measurement gap (generally 6 ms Therefore, the terminal device 202 needs multiple measurement gaps to complete inter-frequency measurement or inter-system measurement, which requires multiple interruption of service transmission of the terminal device 202. In addition, due to the long measurement time, the time for the network device 202 to select a carrier for the terminal device is further extended, which affects the gain of carrier selection.

In order to ensure the service throughput rate of the terminal device and shorten the time for the network device to determine the signal quality information of different frequencies, an embodiment of the present application provides a method for determining signal quality information of a frequency point. This method can be applied to a communication system with a multi-frequency scenario, such as the communication system shown in FIG. 2. Referring to Figure 3, the process of the method includes:

S301: The network device obtains signal quality information of a first frequency point measured by the terminal device, where the first frequency point is a frequency point used by a serving cell accessed by the terminal device.

Wherein, the signal quality information of the first frequency point is obtained by the terminal device through co-frequency measurement. Wherein, the signal quality information of the first frequency point includes signal quality parameters of the first neighboring cell. The first neighboring cell is a neighboring cell of the serving cell that uses the first frequency point, and is also called a co-frequency neighboring cell. The number of the first neighboring cell may be at least one.

Optionally, the network device may, but is not limited to, obtain the signal quality information of the first frequency point measured by the terminal device in the following manner:

Manner 1: The network device may send measurement configuration information to the terminal device to notify the terminal device to perform intra-frequency measurement. Wherein, the measurement configuration information may include the following information: a frequency point to be measured (the first frequency point), a list of cells to be measured (the first neighbor cell list), and signal quality parameters to be measured, Report method, etc.

S302: The network device determines the signal quality information of the second frequency point according to the signal quality information of the first frequency point and the stored first mapping relationship, where the second frequency point and the first frequency point Different, the first mapping relationship is the mapping relationship between the signal quality information of the first frequency point and the signal quality information of the second frequency point.

Optionally, when there are multiple second frequency points in the communication system, the number of corresponding first mapping relationships is also multiple, that is, each second frequency point corresponds to one first mapping relationship. The first mapping relationship corresponding to any second frequency point is used to determine the signal quality information of the second frequency point.

Optionally, the first mapping relationship corresponding to each second frequency point is obtained after modeling the signal quality information sample data of the first frequency point and the signal quality information sample data of the second frequency point.

Wherein, the signal quality information sample data of the first frequency point includes: the signal quality information of the first frequency point measured by multiple terminal devices that access the serving cell multiple times. The signal quality information of the first frequency point measured by each terminal device includes the signal quality parameter of the first neighboring cell.

The signal quality information sample data of the second frequency point includes: the signal quality information of the second frequency point measured by multiple terminal devices that access the serving cell multiple times. The signal quality information of the second frequency point measured by each terminal device includes the signal quality parameter of the second neighboring cell. The second neighboring cell is a neighboring cell using the second frequency point and the serving cell, and may also be called an inter-frequency neighboring cell. The number of the second neighboring cell is at least one.

Hereinafter, taking the computing device as the network device as an example, the maintenance process of each mapping relationship by the network device will be described in detail.

The steps for the network device to maintain the first mapping relationship corresponding to any second frequency point include:

A1: The network device collects multiple pieces of first sample data.

In this step, the network device multiple times notifies multiple terminal devices that access the serving cell managed by the network device to perform intra-frequency measurement, inter-frequency measurement or inter-system measurement; The signal quality information of the first frequency point measured by intra-frequency measurement, and the signal quality information of the second frequency point measured by the multiple terminal devices through inter-frequency measurement or inter-system measurement.

Wherein, a piece of first sample data contains the signal quality information of the first frequency point obtained by the network equipment notifying the terminal equipment of the same frequency measurement at the same time, and the second frequency point obtained by notifying the terminal equipment of the inter-frequency measurement or the different system measurement. Signal quality information of frequency points.

As an example, in the first sample data collection stage for multiple times, the terminal device that the network device notifies to perform neighbor cell measurement each time may be the same or different, which is not limited in the embodiment of the present application.

In a possible implementation manner, when the first sample data is collected at any time, the network device notifies the terminal device that performs intra-frequency measurement and the terminal device that performs inter-frequency measurement or inter-system measurement may be the same or different. This is not limited in the embodiments of this application.

In another possible implementation manner, when the first sample data is collected at any time, the network device can also be implemented by a traditional method. For example, the network device sends measurement configuration information to the terminal device to notify a certain terminal device to perform neighbor cell measurement, where the measurement configuration information includes the frequency point to be measured (the first frequency point or the second frequency point), A list of neighboring cells to be measured, signal quality parameters to be measured, reporting methods, etc. The terminal device performs neighboring cell measurement (same frequency measurement, different frequency measurement or different system measurement) according to the measurement configuration information, and sends the generated measurement report to the network device according to the configured report mode.

A2: The network device uses machine learning technology to model multiple pieces of collected first sample data to obtain the first mapping relationship.

Optionally, the network device may use machine learning techniques such as neural network, support vector machine, genetic algorithm, etc. to perform modeling, which is not limited in the embodiment of the present application.

A3: The network device monitors the accuracy of the first mapping relationship. When the accuracy of the first mapping relationship is low, the network device stops using the first mapping relationship and can repeat Steps A1 and A2, or repeat step A2, update the first mapping relationship.

Optionally, the network device may, but is not limited to, monitor the accuracy of the first mapping relationship in the following manner.

After the network device uses the first mapping relationship to determine the signal quality information of the second frequency point each time, and selects a target cell for the terminal device based on the signal quality information of the second frequency point, the network device Update the cell configuration success rate.

Manner 2: The network device periodically tests the first mapping relationship.

In this manner, the network equipment can notify the terminal equipment that accesses the serving cell to perform intra-frequency measurement, inter-frequency measurement or inter-system measurement, to obtain signal quality information at the first frequency and signal at the second frequency. Quality information. Then, the network device uses the obtained signal quality information of the first frequency point and the signal quality information of the second frequency point as test data, and the network device uses the signal quality information of the first frequency point in the test data as test data. The quality information and the first mapping relationship are calculated to obtain the signal quality information of the second frequency point. Finally, the network device judges the calculated difference between the signal quality information of the second frequency point and the signal quality information of the second frequency point in the test data, and when the difference is less than a set difference threshold, It indicates that the accuracy of the first mapping relationship is high; when the difference is greater than or equal to the set difference threshold, it indicates that the accuracy of the first mapping relationship is low.

Through the above step A3, the network device can ensure the accuracy of the first mapping relationship, so that when the first mapping relationship is used to calculate the signal quality information of the second frequency point, the calculated second frequency point can be reduced. The error between the signal quality information of the frequency point and the actual signal quality information of the second frequency point.

The steps for the network device to maintain the second mapping relationship corresponding to any second frequency point include:

B1: The network device collects multiple pieces of second sample data.

In this step, the network device multiple times notifies multiple terminal devices that access the serving cell managed by the network device to perform co-frequency measurement; and then receives the first frequency measured by the multiple terminal devices through co-frequency measurement. Point's signal quality information. The network device obtains the load information of the first neighboring cell from the network device that manages the first neighboring cell every time it notifies the terminal device to perform intra-frequency measurement, and receives the report from the terminal device that accesses the serving cell. The spectrum efficiency of the serving cell. The first neighboring cell is a neighboring cell of the serving cell that uses the first frequency point, and is also called a co-frequency neighboring cell.

Among them, a piece of second sample data includes: the network equipment once notifies the terminal equipment to perform the same frequency measurement and obtains the signal quality information of the first frequency point, this time when multiple terminal equipments accessing the serving cell perform the same frequency measurement The load information of the first neighboring cell, and the spectrum efficiency of the serving cell when multiple terminal devices accessing the serving cell perform co-frequency measurement this time.

B2 and B3 are the same as steps A2 and A3, and will not be repeated here.

Optionally, the network device may perform step B1 when performing step A1. In this way, the signal quality information of the first frequency point obtained by the same-frequency measurement by the terminal device each time can be used as sample data in a piece of first sample data, or as sample data in a piece of second sample data.

The steps for the network device to maintain the third mapping relationship corresponding to any second frequency point include:

C1: The network device collects multiple pieces of third sample data.

In this step, similarly, the network device acquires the signal quality information of the first frequency point as in the step A1. The network device obtains the load information of the second neighboring cell from the network device that manages the second neighboring cell every time it notifies the terminal device to perform inter-frequency measurement or inter-system measurement, and receives access to the serving cell. The terminal device reports to obtain the spectrum efficiency of the second neighboring cell. Wherein, the spectrum efficiency of the second neighboring cell is obtained when the terminal device obtains the signal quality information of the second frequency point through inter-frequency measurement or inter-system measurement. The second neighboring cell is a neighboring cell using the second frequency point and the serving cell, and may also be called an inter-frequency neighboring cell.

Among them, a piece of third sample data includes: the network equipment once notifies the terminal equipment to perform the same frequency measurement and obtains the signal quality information of the first frequency point, this time multiple terminal equipment accessing the serving cell performs inter-frequency measurement or different system The load information of the second neighboring cell during measurement, and the spectrum efficiency of the second neighboring cell when multiple terminal devices accessing the serving cell perform inter-frequency measurement or inter-system measurement this time.

Similarly, C2 and C3 are the same as steps A2 and A3, and will not be repeated here.

Optionally, the network device may perform step C1 when performing step A1. In this way, the signal quality information of the first frequency point obtained by the same-frequency measurement by the terminal device each time can be used as sample data in a piece of first sample data, or as sample data in a piece of third sample data.

It should also be noted that when the computing device is not a network device, the computing device collects sample data through the network device, and monitors each mapping relationship through the network device. When the network device monitors that the accuracy of the mapping relationship is low, the network device notifies the computing device to remodel and update the mapping relationship.
